IT8211 PCI IDE disk controller. The stock kernel driver reports an IT8212 (an IDE RAID 0/1/0+1 controller). However, there is indeed only a IT8211 on the board.

USB - 2 type A connectors (rear - /dev/usb/lp0, front - /dev/usb/lp1) - NEC D720101GJ. The NEC chip supports five USB interfaces, of which only two are connected to the two plugs. Experienced tinkerer can try to add more USB plugs, according to this here.

Power Supply

25W Univive Co., Ltd. "open frame" dual voltage power supply, from the UOP25D/325D series ([1], [2]). The power supply is actually a "brick" power supply without the usual plastic case. The UOP25D/325D series comes in different variations. The differences are the input voltage ranges, and the maximum output current and output voltage stability. 5V ±5%, 0.1A - 2A and 12V ±6%, 0.1A - 1.5A are typical output values.
